Storing custom data on mesh

[masterdon]

Hi Team,

I am working on an editor for room planner using babylon js. I am storing some custom properties for few of the meshes in my scene. 

shearWall.maxXPos = maxXPos;
shearWall.minXPos = minXPos;

These properties are having their use for dragging. there are other properties as well. each one of it having its own purpose.

I need to save all the data and store it in database. so that user can revisit and work from where he have left the design. to export the data, i am using:

var serializedScene = BABYLON.SceneSerializer.Serialize(scene);var strScene = JSON.stringify(serializedScene);

The issue is, the custom properties set are not part of json data above.

Is there a way to store the custom properties which becomes part of serializer above?

Hi again, Masterdon.  Umm... I think scene.metaData and node.metaData... are included in serializations.  Node includes lights, cameras, and mesh... any BJS type scene item that is an extension of node.

Sooo... I suppose... make an object similar to one of our options objects.  var mySuitcase = {};  mySuitcase.maxXPos = whatever;  etc etc etc.

Then... shearWall.metaData = JSON.serialize(mySuitcase);  Does that sound sane?  When it arrives somewhere, JSON.parse it, and re-install the custom properties onto the mesh.... from the mesh's suitcase.

.metaData is your suitcase, but you must pack it before traveling, and unpack it upon arrival somewhere.  With me?  I hope so.  Others may comment... and I could have said something incorrect.  But, I think this is a WAY to do what you wish.  Report back if you discover things, okay?  thx.

".metaData is your suitcase, but you must pack it before traveling, and unpack it upon arrival somewhere."  Just grab a single item without unpacking the entire suitcase.

metaData is exactly for that. you store what you want and reuse its contents save in BDD or file.
